    Will it support 31kHz video out via VGA I wonder? Would love a period-accurate PC in my superstation one.

      I hadn’t thought of that possibility but it would indeed be fantastic!

      I imagine it would...I haven't tried the core, but most of them maintain the original outputs over the VGA port. Even if, for some bizarre reason it didn't, you could just enable the vga_scaler and force it.

      The core is available at github and should run fine on your SS1, afaik. Be aware it's an experimental core.

      There is also a recent fork by github user janisc which is developing a direct 31khz output.

      Speaking to general : To be clear, none of these MiSTer cores include the Voodoo graphics portion discussed in the parent link.

      I doubt that the degree of sheer hyper-optimisation required to get a Voodoo (plus the Pentium to make it meaningful!) into a DE10-Nano necessarily exists. Never-say-never, sure, but also, just-no - hahaha.

      That work is for higher specced boards like the Xilinx discussed.
